Fifty Shades of Grey producer Michael De Luca said a newcomer will be perfect to play Christian Grey, in the film version of EL James's best-selling erotic novel.

The producer of Oscar-winning film The Social Network talked about the movie at the Hollywood Film Awards, before accepting a film-making prize in Beverly Hills, California.

"I feel like everyone has an idea of what these characters look like and sound like, so to present the world with fresh faces where no pre-conceived notions or baggage come with it is best," he told to Los Angeles Times, "It's like casting Superman or James Bond. A fresh face is appropriate."
